. 9 designates removable bolster-j guides which are adaptedto be plaoe'withgin the .enlarged portion 4 of the bolster-receiving p'ening. In the drawing, 1h ave shownrtwo forms of removable fbolstenguidesflhe form of l-ig. 6 being adapted to be liorizont ilyim 'serted into the desired operative. position and 4 the form of Fig. 7 being adapted to be inserted-vertically of the side-frame-proper W'hen the form of'Fig. 7 is employed the upper-member-of the side-frame is provided ed with air openinglo and'the, "eb formed with a' groov'e 11 to receive the removable guidel.

By forming theopening-iO in -the bottom- 1 member and having the groove 11' iii-com munication therewith, the removable-guide may be inserted from the bottom of the side? frame instead of fromthe top as shown. 'lhe form of Fig. 7 is provided with a profecting member 12- adapted to fit into a pocfret i3, and with ano'pening 14 to receive a pin 15. The removable bolster-guide. of the formof" Fig. 6 is provided with'engaging-mernbers 18 which members when the guides are placed. in

position are adapted to'engage a flange ad a'- cent to the enlarged portion of the bolsterreceiving opening. As-shown; these members 16 are located at the upper end of the guides and engage the upper fixed bolsterguides or flanges 7, but if desired they may be placed at the bottom and engage the lower 8i)" fixed bolster-guides .or'fianges -8. When- .placed at the bottom as just described the apertured projections 17 are located on the upper part er the. guides instead of at the I bottom as shown by the drawingl/Then in 35 position the rojections 17 extend beyond the sides of t e enlarged portion of the holtiter-receiving opening and are, joined by pins 18.
